RICHARD JAMES ED'VTARDS, OF GALENA, ILLINOIS.

CAR-TRUCK.

To all whom it may concern:

Be it known that I, RICHARD J. EDWARDS, of Galena, in the county of JoDaviess and Stateof Illinois, have invented certain new and usefulImprovements in Car-Trucks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in car trucks and moreparticularly to guards for preventing the derailment of the truck.

In Patent No. 799,316, granted to me September 1:2, 1905, I show anddescribe a car truck having derailment guards and also show, describe,and claim side bearings carried by the truck bolster and yieldinglysupporting the body bolster, the side bearings being provided withsprings whereby they give or yield under the pressure or weight of thecar body while rounding curves.

The object of the present invention is to provide means whereby theposition of the bearing blocks regulate and control the posi tion of thederailment guard so that the latter will be automatically raised andlowerel as the truck enters and leaves a curve in the track therebypermitting the derailment guard to normally run in a plane above therail except at curves thus avoiding frogs and switches and to be loweredautomat ically into operative position to prevent deailment on curves.

lVith these ends in view the invention consists in certain novelfeatures of construction and combinations of parts as hereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure l is a view in end elevation partlyin section of a truck embodying my invention and Fig. 2 is a view intransverse section through the yielding bearings showing the derailmentguard carrying stirrups.

1 represents a car truck of any approved construction. This truck mayconsist simply of side frames mounted on axles and carrying a bolster orit may be of the form shown in my patent above referred to. The truckbolster or other part of the truck on which the body bolster rests isprovided with the blocks 2 on which the bearing caps 3 rest and move andby which they are guided, springs 4 being interposed between the blocksand caps to hold the latter elevated and up into Specification ofLetters Patent.

contact with the underside of the body bolster 5. With the constructionthus far described it will be seen that in turning a curve the weight ofthe body of the car will be thrown on to the yielding cap adjacent tothe outer side of the curve, thus depressing the latter and it is thisfeature of my patented device that I now utilize for automaticallyactuating the derailment guards. Secured to these caps are the stirrups6 which latter pass downwardly on opposite sides of the bolster andprovided attheir lower ends with a bolt or other cross member 7 whichseats under or engages the derail.- ment guards 8. These guards arepivotally mounted at their inner ends to the bracket 9 depending fromthe spring-board l0, and each guard arm is provided at its outer endwith a lug l3 and shoulder 1%.

To the lug 13 of each guard arm is pivotally attached a shoe 15 capableof vertical movement and each shoe is provided with an inwardlyprojecting lip 16 which en gages the shoulder 14 to retain the shoenormally in line with the guard arm and prevent it from falling belowthe plane of the guard arm. That portion of the shoe immediately to theinside of the rail is pro vided with a depending flange 17 located in aposition when the guard arm and its shoe are lowered to a plane belowthe top of the rail at the inner side of the rail. On a straighttrack,and when the parts are in their normal position, the spring caps 3 andtheir depending stirrups 6 hold the flanges 17 in a plane slightly abovethe tread of the rails and consequently above all switches and frogs,thus obviating altogether all clanger of contact between the flanges ofthe shoe and parts of the track equipment. hen however, the truck entersa curve the weight of the body of the car falling on the cap 3 adjacentto the outer or longer side of the curve depresses the cap thus loweringthe shoe until its flange rests in the plane of and adjacent to theinner face of the rail and in a position to prevent derailment. As thetruck leaves the curve the car body and truck assume their normalposition and the elevation of the spring cap again raises the guard armand its shoe to its normal position above the track.

It is evident that changes in the construction and relative arrangementof the several parts might be made without avoiding my invention andhence I would have it understood that I do not restrict myself to theparticular construction and arrangement of parts shown and described,but,

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,

1. The combination in a car truck, of a yieldable bearing against whichthe weight of the car body falls, a derailment guard having a dependingflange adapted when the guard is lowered to rest adjacent to and in thehorizontal plane of the track rail, and means connecting the derailmentguard and yieldable bearing, whereby the position of the guard withrelation to the track rail is regulated and controlled by the yieldablebearing.

2. In a car truck, the combination with yieldable bearings against whichthe weight of the car body falls, and derailment guards carried by saidtruck and overhanging the track rails, of means connecting theyieldouter ends of the arms, each shoe having a depending flange toengage the inner face of the rall and means connecting said arms andshoes with the y1eld1ng bearings whereby the positions of the shoes withrelation to the rails are regulated and controlled by the yieldingbearings.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
